Intestinal ischamemia in a child due to polyarteritis nodosa: a case report.

ABSTRACT

Polyarteritis nodosa (PAN) is a rare type of childhood vasculitis. We report the case of a 10-year-old boy who was referred to our hospital following an appendicectomy with fever, abdominal pain, vomiting, diarrhoea, weight loss, joint pains and skin rash. Shortly after admission, he developed peritonitis, and an emergency laparotomy revealed ischaemia of the jejunum which required partial resection. Histologic examination of the resected bowel showed features consistent with PAN. He was treated with steroids and cyclophosphamide. Nineteen months later, he is asymptomatic and thriving. PAN should be included in the differential diagnosis if a child with constitutional symptoms also has gastrointestinal complaints or develops an acute abdomen.
